* Primitive Types
   * Common
     * bool
     * char
     * int  (= int32)
     * uint  (= uint32)
     * float  (= float64)
     * decimal
     * number  (= decimal, change with -number: option)
     * dynamic (see DynamicType)
   * Explicit Sizes/Sign
     * int8, int16, int32, int64
     * uint8, uint16, uint32, uint64
   * PrimitiveTypeMembers
 * Complex Types
   * Class
     * Single inheritance
     * Heap-based
     * Popular classes
       * Object, String, !StringBuilder, Exception
       * List<of T>, Dictionary<of K, V>, Set<of T>
       * Stack<of T>, Queue<of T>
       * !TextWriter, !TextReader, !StringWriter
   * Struct
     * No inheritance (other than Object)
     * Value-based
     * Popular structs
       * !DateTime, Color (System.Drawing)
   * Interface
     * Multipile inheritance
     * No code implementation
     * Popular interfaces
       * IEnumerable, IEnumerable<of T> (but use T* instead; see streams below)
       * IComparable, IComparable<of T>
 * Nilable Type
   * foo? - can be "foo" or "nil"
   * applies to all types
   * "dynamic" implies "dynamic?" meaning you can always pass "nil" where "dynamic" is expected
 * Streams
   * foo* - walkable collection of zero or more objects of type foo
   * See StreamType
 * Working with types at run-time
   * You can get the type of "x" with "x.getType"
   * You can make instances with a type at run-time
     * t = x.getType
     * obj1 = t()
     * obj2 = t(0, 0)
 * Generics
   * Classes, interfaces and structs can all be generic--parameterized by type.
   * These are identical to .NET generics as found in C# and VB.
   * Examples: List<of int>, List<of String>, Dictionary<of String, int>
   * The general form is: Name<of T, U, ...>
   * You can declare your own
   * You can overload by number of type arguments. In other words, Foo<of T> and Foo<of T, U> are two different types.
   * Methods can be generic: def foo<of T>(a as T, b as T)

TODO: arrays, passthrough, vari, local var type inference, greatest common denominator
